Abstract

Water-soluble fibre-reactive dyestuffs containing one or two fibre-reactive groups of the vinylsulfone series and one or two fibre-reactive groups of the fluoro-s-triazinyl-amino series. These dyestuffs can be applied on fibre materials containing hydroxy and/or carbonamide groups by known application and fixation techniques for fibre-reactive dyes to yield deep and fast dyeings on these materials.
